SHUTTLE-DRIVING MECHANISM FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 399,701, dated March 19, 1889.

Application filed April 27, 1888.

To aZZ whom it may concern:

Be it known that I, LOUIS SCHULTZ, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Shuttle Mechanism, of which the following is a specification.

My improvement relates particularly to shuttle mechanism for sewing-machines having a gang or large series of needles and corresponding shuttles.

I will describe a shuttle mechanism embodying my improvement, and then point out the novel features in the claims.

In the accompanying drawings, Figure l is a plan or top view of a portion of the race mechanism and a corresponding portion of the shuttle carriers or drivers. Fig. 2 is a sectional elevation of the mechanism shown in Fig. 1. Fig. 3 is a transverse section taken at the plane of the dotted line m at, Fig. 2.

Similar letters of reference designate corresponding parts in all the figuresj A designates a number of bars severally having one plane side, a, and the opposite side, a, provided with a concavity. These bars are supported upon stationary bearer-bars B B screws or other devices being employed to secure them at the end portions to these bearer-bars.

The bars A are so arranged with reference to each other that the side a having the concavity of each of said bars will be opposite the flat side a of the next adjacent bar. The lower portion of the side a of each of the bars A is shown as vertical, and consequently parallel with the plane side a, of the next adj acent bar.

0 designates shuttles working in the raceways consisting of the spaces between each two adjacent bars. The convex sides of the shuttles fit the concavities in the sides a of the bars A. The fiat sides of the shuttles bear against the plane sides a of the bars A.

D designates shuttle carriers or drivers severally consisting of rods working horizon tally opposite the spaces between the lower vertical portions of the sides a of the bars A and the plane sides of the next adjacent bars A. These shuttle carriers or drivers are provided with upright pins d,.(shown as made perfectly straight,) and at a short dis- Serial No, 272,038. (No model.)

tance therefrom with other pins, cl,whose upper ends are bent over to form hooks. These pins d 61 extend up into the raceways between the bars A. The pins d are sufficiently distant from the pins cl to accommodate shuttles between them. The shuttles may be dropped into the raceways with their noses or sharpened ends inserted under the hookshaped ends of the pins d, and with their other ends adjacent to the pins (1. If, then, the shuttle carrier or driver rods D be reciprocated. longitudinally, the shuttles will be carried or driven longitudinally through the raceways. The rods D work in grooves h b in the bearer-bars B B The bearer-bar B is provided with a cap-plate, 5 which extends across the grooves b and across the rods B, and being fastened in place by screws or like devices maintains the bars D in their proper positionsor, in other words, prevents them from any vertical movement relatively to the bearer-bars B The rods D at one end are made somewhat thin and resilient and provided with hooks d consisting of pins that extend downwardly from such resilient portions. These pins engage with holes or cavities e in a bar, E. The bar E is reciprocated by means of a crank-arm, G, and .connectingrod H, said bar E being guided upon rods 1, extending from the bearerbar 13. By lifting up the resilient end portion of the rods D they may be disengaged from the bar E, and they may, if desired, then be slid out of their operative positions.

WVhat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with the race-bars A, connected to the stationary bearer-bars BB and having sides 0., provided with concavities, and opposite plane or flat sides, a, of the shuttle carrier or driver rods D, provided with hooks and working in grooves provided in the stationary bearer-bars B 13 a cap-plate on the bearer-bar B holding the shuttle carrier or driver rods D, and the reciprocating bar E, to which said shuttle carrier or driver rods are detachably connected, substantially as specified.

2. The combination, with the race-bars A, connected to the stationary bearer-bars B B and having sides a, provided with concavities, and opposite plane or fiat sides, a, of the shuttle carrier or driver rods D, having resilient ends provided with hooks and Working in grooves provided in the stationary bearer-bars B B a cap-plate on the bearerbar B holding the shuttle carrier or driver rods, and the reciprocating bar E, furnished with holes or cavities for receiving the pins LOUIS SCHULTZ.
